purchase these wheels!Name - AdminJust regular 8mm bearings and regular spacers. They are called 608 bearings.Name - what size bearings and spacers do i need for the kryptonics 70mm derby skates?Name - what kind of bearings and spacers do i need for these wheels?

I tried using them for hockey thinking that a bigger quad wheel would be helpful in the speed department and it was the exact opposite. Overall a bad experience! So stick to 62mm or 65mm for Quads, trust me! Also, the larger size made them VERY heavy! Almost to the point of being clumsy, so stick to off-roading on rough terrain with them, not a smooth outdoor hockey rink!

These will roll over anything, and have great sustain on a stride. They are soft, very bouncy, heavy enough so you are getting your workout even without striding as much. Hills with debris? Roll over that stuff. They are not meant to increase your agility, try a smaller wheel for that.

I've had two sets of Kryptonics 70mm red wheels on my outdoor skates (Sure Grip #7 Joggers on basketball shoes, yeah, I mounted them myself) dating back over 20 years. I just shopped for new wheels and the Route 70mm won out. I needed 70mm wheels to get proper contact for my California Skate Brakes. Don't think the opaque Kryptonics 70mm reds are around any more. The Routes are see-through and have that cartoon-like stuff on the outside. I found putting new bearings in the Routes quite a bit tougher than the old Kryptonics. At first I thought they must take 7mm bearings, but soon realized you just have to force them in there. I took a plumbing pipe, put a piece of duct tape on the end and used it to punch the bearings in with the help of a ball peen hammer.

These wheels are amazing. I went from a 65 millimeter indoor wheel that made skating outdoors (sidewalks, asphalt) impossible to these- The route 70's make things so smooth and roll so easy, there is no comparison. If you skate outdoors, you NEED these whees!!

First it was 62s then 65s and now 70s and I gotta say I LOVE these wheels!!! I am an outdoor fitness skater, living in San Francisco and I skate all over the city. The bigger wheel is smoother and safer for my type of skating. Yeah, it takes more muscle to push but that just makes my legs look fantastic.

my red kryptos will roll over just about anything. they ARE heavier than standard skate wheels, but just about anything made for outdoor skating and with this durometer is likely to be rather weighty. with the right clean bearings these wheels are FAST. they absorb a lot of shock from rough surfaces and help to keep you rolling rather than knee-bumping, dead-stopping on twigs or sidewalk cracks. i'm even comfortable barreling downhill on city streets with 'em.

they're not for the rink. they're not for dancing or jam-skating. they're not for the skate parks, but they're top-notch for serious rough-riding.
